| Research Abstract |
We have investigated numerically and theoretically the quantum dynamics in one-dimensional quantum systems driven by time-periodic external fields. Our focus is on the control of quantum dynamics in a spatially periodic system driven by a time-periodic field. Out theoretical analysis based on quantum-classical correspondence provides an intuitive way to understand the quantum transport phenomenon. We have demonstrated that the effective group velocity, which is calculated from energy dispersion, well explains the wave-packet dynamics that was observed in experiments.
